Hydrodynamic modeling is carried out by reservoir engineering department. The department is in charge of all reservoir engineering aspects:
- reservoir engineering progress analysis;
- analysis of the hydrodynamic surveys and PLT on wells, including sampling and testing;
- fluid samples analysis, including gas condensate studies;
- recommendations on how to enhance the development, options justification and search for the best well production modes and methods;
- setting the requirements for development monitoring and additional study of reservoir production;
Calculation of process performance through analytical and numerical methods, including constructing and adapting 3D hydrodynamic models in the most widely used simulators, at the customer's discretion.
Ultimately the department provides an estimation of recoverable and profitable hydrocarbon reserves and the best scenario for the target reservoirs and deposits engineering. For understudied deposits, unallocated areas or with a very recent development history, it is imperative to compare the oil recovery factor with data from similar reservoirs of the same region. If there is sufficient information available, displacement analysis is carried out.
For gas and gas condensate fields, recoverable (drained) resources may be estimated via material balance method if required conditions are met. Moreover, compositional 3D hydrodynamic modeling is available for targets with complex fluid composition (high initial condensate gas, volatile oil, etc.).
The department staff has run numerous projects in fields with low-permeability reservoirs and hard-to-recover reserves. In such cases, we envisaged the use of horizontal wells (with horizontal sidetrack up to 2 km), multi-stage hydraulic fracturing and a variety of physical, chemical and thermal EOR methods. SAGD, CSS, THAI and in-situ combustion (fire flooding) modeling was carried out in a hydrodynamic simulator.
Oil & gas field development engineering
During project development CJSC MiMGO elaborates environmental measures that meet the requirements of the existing regulations and legislation.
Environmental priorities and key guidelines:
- On-going soil, surface and groundwater, atmospheric air and geological processes monitoring;
- Environmental measures aimed at preserving fauna and flora in the subsoil area during subsoil development;
- Disposal of industrial and household waste and comprehensive measures aimed at preserving the geological environment during subsoil development;
- Comprehensive measures to prevent and address oil spills as well as other emergencies;
- Environmental measures for subsoil, air and land preservation;
Other activities required.
